[Rosa cathayensis (Rehder & E.H.Wilson) L.H.Bailey, more...]
Fields, pastures, fencerows, prairies and savannas, roadsides, thickets, hillsides and ridgetops, river islands, higher ground on edges of marshes and open wetlands, old quarries and gravel pits, dumps; disturbed forest edges and clearings and sometimes forming impenetrable thickets in the interiors. This species is introduced from Asia and was first collected in 1957. It is an aggressive weed that outcompetes native vegetation and it can form very large patches that are quite formidable. The high-arching canes often reach out along trails, their stout prickles snagging on passersby. The small, white flowers held in an erect panicle are unlike any of our other roses. Multiflora rose is common across the southern part of the state and in the Driftless Area and has steadily moved northward.
